Fast Scanner PDF Scan App Data API

Cool Mobile Solution · Utilities

Fast Scanner - PDF Scan App is Cool Mobile Solution's free document scanner for Android: point the camera at a receipt, invoice or whiteboard and the app crops, enhances and exports the page as PDF or JPEG, with optional text recognition and automatic backup into the user's own cloud storage. It serves home-office and small-business users across the US, India, Brazil and Indonesia who use their phone as the filing cabinet for paper paperwork.

As a data source, the app exposes the full lifecycle of a scanned document. A cloud text-recognition call returns the extracted text for each page; auto-upload then files the PDF or JPEG into Google Drive, Dropbox or OneDrive and tags every remote file with a docID and folderName so the same scan can be found, skipped or updated instead of duplicated. Dropbox keeps a JSON inventory keyed by checksum and revision, background workers report runAttemptCount per cloud service, and a privacy channel accepts erasure requests identified by firebaseInstanceId and hashDeviceId. Bookkeeping bots, multi-cloud vault reconcilers and data-rights desks build on these fields.

Fast Scanner is Cool Mobile Solution's free camera-to-PDF scanner for Android, turning paper receipts, invoices and contracts into searchable digital documents for users across the US, India, Brazil and Indonesia. Behind its scan-and-share screens sits a document dataset: cloud OCR text for each captured page, PDF and JPEG copies filed into the user's own Google Drive, Dropbox or OneDrive under a docID key, and per-install identity records behind its privacy-request channel. That dataset feeds bookkeeping bots, multi-cloud vault reconcilers and data-rights fulfilment desks.

Where teams use this data

Searchable archive of paper invoices
A bookkeeping bot posts each scanned invoice page to POST /v1/ocr/extract, stores the returned text beside the PDF, and later finds the Drive copy via the docID custom property on GET /v1/cloud/drive/files/search.
Multi-cloud document vault
An integration watches auto-upload: Drive files tagged with docID and folderName, Dropbox jpegs.json rows (docID, checksum, revision), and OneDrive folder children, so the same scan is reconciled across three vaults.
Privacy-request fulfilment
A DSR desk submits POST /v1/privacy/erasure-requests with firebaseInstanceId, hashDeviceId, appVersion and packageName, then confirms success before closing the ticket.
Upload-worker health
Ops dashboards ingest POST /v1/telemetry/upload-workers (runAttemptCount, service, installationId) to see which cloud backend is retrying and how often.

Frequently asked questions

How does Fast Scanner extract text from a scan?

From the Cloud OCR screen the app uploads page images as multipart filename[N] parts to POST /v1/ocr/extract. The JSON reply carries a success flag, the extracted text shown on the OCR result screen, and an optional message when recognition fails.

How are scanned PDFs found again on Google Drive?

Auto-upload tags each Drive file with the custom properties docID and, optionally, folderName. The file-search call GET /v1/cloud/drive/files/search matches on those properties so the worker can skip or update the existing file instead of duplicating it.

Which cloud accounts can Fast Scanner auto-upload to?

Google Drive (OAuth scope drive.file), Dropbox (file upload plus a jpegs.json inventory) and OneDrive (folder children listing and item content writes). Background workers also report which backend they are using through POST /v1/telemetry/upload-workers with the service field.

How does a user request deletion of Fast Scanner cloud data?

The data-deletion screen posts firebaseInstanceId, an MD5 hashDeviceId, appVersion and packageName to POST /v1/privacy/erasure-requests. The JSON reply is a success flag plus a message, and the client retries against a backup route if the primary call fails.
